APPLICATION OF RECYCLED AGGREGATE CONCRETE FOR STRUCTURAL CONCRETE. PART 2 - FEASIBILITY STUDY ON COST EFFECTIVENESS AND ENVIRONMENTAL IMPACT

A study on the use of recycled aggregate concrete for structural concrete was carried out under the concept of Life Cycle Assessment (LC A) for environmental management of construction utilizing recycled products. The use of these products are often discarded, especially where existing electric power stations are rebuilt or upgraded in order to meet increasing power demands. In pursuing the reuse of recycled materials, the basic policy was composed of three items. These include quality assurance, reduction of environmental impact and construction cost. The study was divided into three main parts, (i) feasibility study on the reuse of recycled aggregate concrete, (ii) experimental study on the quality of recycled aggregate and (iii) concrete made with this material. This paper presents the results of the feasibility study on the cost effectiveness and environmental impact (CO2 emission volume). The findings of the feasibility study is used as a replacement model for thermal power stations. Based on the investigation and the analysis of results, valuable data were obtained regarding the concept and practice to the reuse construction debris based on LCA. Keywords: Life cycle assessment, Feasibility study, Recycled aggregate, Recycled aggregate concrete, Cost effectiveness, Environmental impact, Simulation, Thermal power station.
